7.8.4 AC Power and Steady-state Systems. When a system is supplied with AC power, the instantaneous power and thus the energy transfer rate on the boundary changes with time in a periodic fashion. Our steady-state assumption requires that nothing within or on the boundary of the system change with time.

A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential
From theory to application. Ampacity is not simply a line item in a code table, but rather a question of heat flow balance. It is highly dependent on (a) the surroundings of a cable and (b) how effectively heat is conveyed away from that cable. The more generated heat that is retained near the cable, the hotter that cable will operate.
Flow batteries: Design and operation. A flow battery contains two substances that undergo electrochemical reactions in which electrons are transferred from one to the other. When the battery is being charged, the transfer of electrons forces the two substances into a state that''s "less energetically favorable" as it stores extra energy.
